Product Information

The TL071 offers low distortion characteristics and wide bandwidth, enabling precise and accurate signal amplification. It also has low noise characteristics, which can minimize the influence of external noise during signal processing.

Their high input impedance and low input bias voltage allow them to connect to a variety of signal sources and devices. Additionally, it is equipped with a high-output driver to maintain stable output despite changes in resistance value.

The TL07xx JFET-input operational amplifier family is designed to offer a wider previously developed operational amplifier. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. It is known for its high input impedance, low input bias current, and low offset voltage, making it suitable for various analog applications.

These low noise JFET input operational amplifiers combine twostate–of–the–art analog technologies on a single monolithic integratedcircuit. Each internally compensated operational amplifier has well matchedhigh voltage JFET input device for low input offset voltage. The BIFET technology provides wide bandwidths and fast slew rates with low input biascurrents, input offset currents, and supply currents. Moreover, the devicesexhibit low noise and low harmonic distortion, making them ideal for use inhigh fidelity audio amplifier applications.
